The day has finally come: Google has started shipping Google Glass to the lucky few early adopters. Now that it's shipping, Google has also unveiled a lot more about the API and the specifications of the device itself. While the company had already given out substantial details at earlier occasions, there are still a few surprises here.

Simple. Brand-building. Being first in can be worth a lot down the line, but it's a real risky game. Think of VisiCalc. Google is hoping that app developers want to be the brand that Glassholes recognise first once the competition comes along.

There will be advertising. It just won't be banner ads. Google don't know what it will be yet fully and want use-cases shoved in front of them (for free) first.
